The television circuit is suitable for use with a television picture signal originating from a tele-cine converter (1) which operates at a cine film display rate of 24 frames per second and a 60 Hz field frequency. The picture signal has cycles of alternately two and three field periods with the same picture information which, on display, results in flicker phenomena. To reduce flicker on display of the picture signal on a display screen, the picture signal is applied directly and by a delay device (5) producing a time delay of at least two or more whole field periods to a signal combining circuit (6) which is in the form of a matrix circuit and is followed by a change-over circuit (7). The matrix circuit (6) produces signal combinations in the output picture signal which on display result in flicker reduction.
